BACKGROUND OF THE INVENTION

1. Field of the Invention

The present patent application for industrial invention relates to an element for sliding racks made of metal wire and located inside furniture, in particular modular kitchen cabinets.

2. Description of Related Art

As it is known, kitchen cabinets are commonly equipped with removable internal racks, whose bottom consists in a grid obtained by soldering multiple rod irons, while the bearing structure is usually made up of a frame obtained with metal profiles or pressed metal plates suitably shaped to act as slide guides.

An additional inconvenience of practical nature is represented by the fact that the use of these telescopic guides requires the presence of suitable means to fix the guides to the rack frame.

BRIEF SUMMARY OF THE INVENTION

The main purpose of the present invention is to provide a solution to both inconveniences, through the realisation of an element capable of acting as cover for the telescopic guides and at the same time as connection element between guides and rack.

BRIEF DESCRIPTION OF THE DRAWINGS

For major clarity the description of the multi-purpose element for sliding metal racks according to the present invention continues with reference to the enclosed drawings, which are intended for purposes of illustration and not in a limiting sense, whereby:

FIG. 1 is an exploded perspective of a metal rack with two box-type bars with upturned-U cross section mounted on the sides;

FIG. 2 is an axonometric view of one box-type bar with upturned-U cross sections seen from the back, that is from the opening for the telescopic guide;

FIG. 3 is an axonometric view of an ordinary telescopic guide to be inserted and hidden inside each box-type bar with upturned-U cross section;

FIG. 4 is a section of the box-type bar with plane IV—IV of FIG. 3.

DETAILED DESCRIPTION OF THE INVENTION

With particular reference to FIGS. 2 and 4, the multi-purpose element for sliding metal racks according to the present invention consists in a box-type bar (1) with upturned-U cross section that can exactly house and hide a telescopic guide (2) of known type. 

1. Multi-purpose elements in combination with a sliding metal rack, the elements each consisting of in a box-type bar (1) with upturned-U cross section, a telescopic guide (2) being housed within the box-type bar (1), the guide having an internal wall having a tooth (2 b) formed thereon, the metal rack (4) having two sides on a body, one box-type bar (1) being fixed to each of the two sides of the metal rack (4), becoming an integral part of the metal rack (4), acting as bearing structure of the body of the metal rack (4), each box-type bar (1) being provided with means for preventing each box-type bar from overturning and exiting from the guide (2), the guide being provided with means for cooperating with the preventing means on each box-type bar, an anti-loosening means of consists an elastically flexible tongue (7) located on an inner wall of each box-type bar (1), the inner wall of the box-type bar being provided with two notches (8) capable of isolating the flexible tongue (7), the flexible tongue (7) having an internal face having a section (7 a) with higher thickness provided with a seat (7 b) that can house the tooth (2 b) located on the internal wall of the guide (2).
 2. Multi-purpose elements in combination with a sliding metal racks the elements each consisting of a box-type bar (1) with upturned-U cross section, a telescopic guide (2) being housed within the box-type bar (1), the metal rack (4) having two sides on a body, one box-type bar (1) being fixed to each of the two sides of the metal rack (4), becoming an integral part of the metal rack (4), each box-type box acting as bearing structure of the body of the metal rack (4), each bar (1) having on a front end (1 d) an upper wall, a seat (9) being provided on the upper wall and including a bracket (10) which is fitted and tightened on an internal face of a front panel (11) to obtain a drawer with the metal rack as an internal compartment.
 3. Multi-purpose elements in combination with a sliding metal rack, the elements each comprising a box-type bar (1) with an upturned-U cross section, a telescopic guide (2) being housed within the box-type bar, the metal rack (4) having two sides on a body, one box-type bar (1) being fixed to each of the two sides of the metal rack (4), an upturned hook (2 a) being formed on an upper surface of the telescopic guide (2), each box-type bar (1) having an opening on a rear end (1 e) thereof, a niche (3) being formed within the opening near the rear end of each box-type bar, the upturned hook (2 a) engaging the niche (3) when the telescopic guide has been completely inserted into the respective box-type bar such that vertically separation of each box-type bar and the rack attached thereto from the telescopic guide is prevented.
 4. Multi-purposes element in combination with a sliding metal rack, the elements each comprising a box-type bar (1) with an upturned-U cross section, a telescopic guide (2) being housed within the box-type bar, the metal rack (4) having two sides on a body, one box-type bar (1) being fixed to each of the two sides of the metal rack (4), an upturned hook (2 a) being formed on an upper surface of the telescopic guide (2), each box-type bar (1) having an opening on a rear end (1 e) thereof, a niche (3) being formed within the opening near the rear end of each box-type bar, the upturned hook (2 a) engaging the niche (3) when the telescopic guide has been completely inserted into the respective box-type bar such that vertically separation of each box-type bar and the rack attached thereto from the telescopic guide is prevented, each telescopic guide further having an internal wall having a tooth formed thereon, an elastically flexible tongue (7) located on a wall of each box-type bar, the wall of each box-type bar being provided with two notches (8) capable of isolating the flexible tongue, the flexible tongue having an internal face having a section (7 a) with a higher thickness provided with a seat (7 b) that can house the tooth located on the internal wall of the guide such that the guide is automatically stopped inside the bar and longitudinal separation of the guide from the box-type bar is prevented.
